I am restoring a 1968 390 GT fastback. Did the dress-up kit for the engine compartment (chrome air cleaner and valve covers) come from the factory on every 390 GT or was this a separate option? I have never seen it listed as an option on a Marti Report.
-
The dress up parts were part of the S code 390 option. The X code 390 did not have those parts.
-
I respectfully disagree. There were S code cars that did not receive the chrome lid, oil cap or valve covers. Build sheets indicate a C8OF-A (chrome) and a C8OF-B (not chrome) air cleaner.
Im interested to know if the breakdown is strictly GT option or not? I havent found the answer to that yet.
I would expect the GT cars to have it. I wonder if non GTs could have ordered the dress up ?
We are in agreement on the X codes...no dress up there (I think) 😉
The infamous X Code, I owned an X code coupe once. It was the shell only. Unfortunately it was so far gone, I sliced it up and took it to work one piece at a time. I didnt want to fill the dumpster all at once. 😬
-
That is interesting Pete. I do not know if I have ever seen a 67-68 S code non-GT. I would like to see any documentation that you may have. I have a 12-12-67 Ford sales addendum that states: 390 -cu. in. V8 engine option now only available with GT equipment group. So, if you think only non-GT cars would have had painted air cleaners, they will have to be 67s and early 68s.
-
Will you provide additional information on the car, such as build date, options (GT or non GT), and DSO (export)? I think with the additional information we can more clearly answer your question.

Thanks for the feedback. It is a 390 GT 4-speed fastback built in San Jose in January 68 and delivered to Los Angeles.
-
I can post more ...standby. My response is for 1968 only.
However Im aware there were 1,138 -390 cars in 1967 that were not GTs.

I believe this is the drawing from the parts manual. The C8OF-A is referred to as "GT" which is the chrome lid. I believe that was actually available on a non GT car as well.

This car was on eBay . The buck tag indicated it was a GT. Chrome lid, chrome valve covers, chrome oil cap (and I assume dipstick)

This 390 build sheet (different car) was posted on VMF, the box "B-4" indicating a "GT" model is not checked. I believe the car is not a GT car.
Supported by owner's comments "When I bought the car in 1981 is came with std-Rear Valance, left and right "390" ponies and std Mustang pop-open gas cap (no GT badges)
Interestingly, I responded to the post. I apologize for being a dickhead in my younger years ;) So, I think there was a possibility of getting the chrome parts on a non-GT. I also think The C8OF-B (blue lid) was also available
I guess there is some possibility that the C8OF-B is something other a non chrome air cleaner?
-
My 1968 Microfische identifies the C8OF-A as all 390 but not GT
and the C8OF-B as the chrome style with GT
I guess we have some ambiguity here. I will try to get a picture of that

Here's a picture of ambiguity. Sorry, I couldn't resist.
-
If someone has a GT buildsheet, that might be helpful.
If its a C8OF-B that maybe confirmation that number is chrome
-
Thanks again. Did all 1968 390 GTs come with power front disc brakes and power steering, or were those separate options available with or without the 390 engine and/or GT package?
-
IMHO all S codes came with disc brakes. PS was a separate option.

The chrome engine components were included with the GT option for the S-code engines. Since you have indicated that your car has the GT option I would conclude that it should have the chrome engine components. The previous discussions regarding the X-code engine, and the early production non GT S-Codes are not applicable to your question.
The disc brakes were not included with the GT option in 1968, however, disc brakes were a mandatory option for the GT when optioned with the S-Code engine. P/S was a stand alone option.

Pete, I have copies of 5 different 1968 S-code Mustangs all of them have the C8OF-B air cleaner, except the one you posted (8T03S1116XX). 3 of them are definitely GT's and the fourth one I have the GT Option line is destroyed.

-
Thanks again--Very helpful. If disc brakes were included on the 390 GT, were those always power brakes or was that also a separate option like power steering?
-
Perhaps the drawing posted above is backwards?
If so, the 1968 MPC entry would be correct
The -A is the blue one. That would seem to match the build sheet/car ( a non GT) I posted
The -B being the chrome lid.
-
We have a damaged NOS air cleaner assembly. Been dropped and the elbow is tweaked. Designated C8OZ-9600-B. This version has the round valve on the side, the X code cars do not have the valve as far as I know. As shown in the photo, this is a service part and the box is dated 7/26/69.
-
Very nice 😁
-
Does anyone know why the decal on the NOS Air Cleaner indicates C80F 9600-C? Is this a Service Part Number for Air Cleaner? I thought it was PN for decal but now I'm not sure. I have seen different PNs on decal for same 390 GT air cleaner.

From what I see, the (letter O, not number 0) C8OF-9600-C is the air cleaner assembly part number. The service part number is a single letter swap to C8OZ-9600-C
The FA-41 air cleaner element has a full service part number of B7SZ-9601-A.

This is a 67 S code 390 non GT car engine that was thoroughly vetted on this site during its assembly.

Looking very nice

As nice and authentic looking this engine is detailed I saw a couple of small things that would make it more authentic. I would try and find some of the castle head type bolts for the smog pump pulley like is more typical . The A/C idler pulley should have the bearing cover/cap zinc and not painted black.

The correct industry name is "Place Bolt". The design was intended to act as a locking feature.

The rest of the hardware information is available in this forum's library under topic "Mustang Hardware Spreadsheet 67-68". There are two files, one by part number, the other by application - it's use. The head types are described.

Here's the build sheet and Marti for my 68 "S" code. It's a late build Metuchen car, The tape covered the "GT" block on the build sheet but it's definitely a GT. Has the chrome lid air cleaner with the round air cleaner vacuum door and chrome covers. Also odd that it shows a 55 amp alt. but I think this was covered in a previous post ...

Thanks for posting this

Many years ago, I looked at a 67 S-code convertible (to buy) that was not a GT car. It was a Metuchen built mustang and PIO was not on the buck tag. It had a non-cutout rear valance and turn down exhaust tips, mustang letters and 390 running horse of both fenders. The engine did have chrome valve covers and dipstick but the air cleaner was missing. I am not as organized as Jeff so it may take me awhile to find the pictures that I took.

Not odd because it has the heavy duty battery option according to the Marti which the 55 amp alt and heavy duty C8TF regulator is a part of.

Was the rubber seal across the top of the radiator support (that was attached with staples) only installed on big block cars in 1968?
-

No. The 68 small blocks that I have seen the strip on had the heavy duty cooling option . The strip was meant to direct air through the radiator support and hence radiator instead of allowing it to pass over the top of the support. Maybe a coincidence or maybe tied to that option I'm not sure.
-
I believe six cylinders got the seal as well

Noticed that you have not added a signature to your post so we don't know when and where you car was built so can't give good details for your question about how it was attached :(

Very correct as usual.
If someone want to see some examples there are a number of unrestored cars in that section of the site with them visible. Pus have a fair number of additional pictures ;)

San Jose early January 1968 production S-code GT with extra cooling package but no A/C.
-
Is it correct that the hood seal on the radiator support was installed on Mustangs in 1968 with the Extra Cooling Package option regardless of whether the car was a small or big block, with or without A/C?

Don't believe so but would have to compare pictures with Marti reports to show proof at this point
-
What do you think was the determining factor for installing the hood seal then if both small and big blocks had them--but not all small blocks?

Have not found any original unrestored SB with them in 68 any plants though you can find a fair number of repaired/"restored" cars with them added by owners in the thought that it would help with the efficiently of the car/cooling. Guess that is what you have been seeing at some shows or the internet. ::)
Unfortunately Kevin Marti didn't choose to include the "extra cooling package" in his break down of options and how many cars were produced with it in his book Mustangs by the Numbers
Haven't found a Marti report or buildsheet of a 68 SB Mustang with that option on it except for 68 GT350 but like 67 GT350's that extra cooling package was part of the standard equipment for those cars as written in the specifications but these were not your regular Mustangs. Still looking through more
-
Finished looking through 300-400 68 Marti reports (had more but sort of gave up for the minute ???
Found no cars with the extra cooling package as an ordered option. As far as some models (FE, 6 cylinder and AC) it was likely part of the AC or engine type option. Did find the extra cooling package but that was for a different Ford model (rear big car) built elsewhere in a different plant that where Mustangs were built.
With that said I focused on 68 small block Mustangs and Cougars with AC built at all of the plants and found none of those (unrestored or modified cars) and none of them showed an original hood seal nor evidence of attachment from the pictures I have.

Sorry looks like I skipped over the direct response as we got sidelined with the other questions
Here are a couple of unrestored cars (early 68 S code wo/AC) for example. Seal with staple retainers
7R0xS1094xx (top) and 7R0xS1404xx

This brochure does not mention the engine dress up option. I thought that the chrome was part of the GT package and that cars ordered with 390 without the GT package received no engine chrome.
-
IMHO all S codes came with disc brakes. PS was a separate option.
My Feb '68 SJ fastback is a non-GT S-code car. Manual drum brakes only, but does have power steering. The original motor was gone when I got the car back in the 80's, so I can't confirm if it had the chrome dress-up pieces.

Have owned and seen my fair share of 67 S codes Mustangs and unlike 1969 the chrome valve covers and air cleaner lid was used on all of the 67's
